Headphones — HiFiMAN HE400se

The HE400se is an accessible planar-magnetic over-ear headphone from HiFiMAN, built with a comparatively benign impedance. The HE400se brings HiFiMAN's legendary planar-magnetic driver engineering to an accessible open-back over-ear format.

Key specs that matter

Frequency response spans 20Hz to 20,000Hz within plus-or-minus 10dB. Connection uses a 3.5mm jack. Sensitivity is notably high at 91dB SPL at 1kHz/1mW, with impedance at a comparatively benign 25 ohms. Weight is 396g.

Sound and use context

Expect the exceptionally fast, detailed character HiFiMAN's legendary planar-magnetic driver technology is broadly celebrated for, delivered at an accessible price tier within the brand's broader flagship-tier catalogue.

Pairing

The comparatively benign 25-ohm impedance and notably high 91dB sensitivity make the HE400se compatible with a wide range of sources.

Alternatives

HiFiMAN's own HE600 offers a more accomplished alternative with a wider bandwidth within the same broader planar-magnetic catalogue.
